The main working principle of reverse osmosis water purification equipment is to use the selective permeability of the reverse osmosis membrane, so when the reverse osmosis membrane problems will affect the water quality of the equipment. So how to reverse osmosis membrane components for the diagnosis of failure?
1. Check the operation records. Under the premise that daily operation data records are kept, confirm the system operating conditions and conditions, and investigate whether there are abnormal operating conditions.
2、Add necessary data. Grasp whether the overall performance of the system is declining or partially declining. If the performance of the reverse osmosis system is partially degraded, you can disassemble the membrane element where the problem occurred and check its appearance and the condition of the seals of the connections, etc.
3、Investigation and analysis of the characteristics of the raw water state.
4、Performance testing of the membrane element unloaded from the pure water equipment unit, disassembly and inspection of the membrane element (analysis and cleaning test of the membrane).
